Foreword

Public transport is an essential service and an environmentally attractive transport option that supports the living standards and economic competitiveness of Sydney and the NSW people. It is an inherently sustainable form of transport which can significantly reduce traffic congestion, noise, air pollution and greenhouse gas emissions by encouraging mode shift away from private vehicle use.

The Sustainable Design Guidelines have been a key tool in helping to realise sustainable public transport outcomes. They have been continuously updated since their inception in 2009 to ensure they are relevant and in line with current best practice. The Guidelines are well understood and utilised by our internal and external stakeholders and have also been acknowledged through the receipt of various industry awards over the years.

This version of the Guidelines (Version 4.0) accounts for:

• Developments in industry standard and best practice.

• Whole of life cost assessment.

• Changes in sustainability policy direction.

• Sustainability initiatives that demonstrate equal or reduced (from business as usual) operational and maintenance costs as a measure of their effectiveness.

• Lessons learned from application of previous versions of the Guidelines.

We will continue to monitor and update the Guidelines in line with changes in policy direction, technology and innovation.

1. Introduction

The Gosford Passing Loops project installed a glow path comprising a non-toxic photoluminescent material. This is an Australian first and aims to increase the feeling of safety within the community. The initiative received

compliments from the community and Council is looking to apply the initiative elsewhere within the area.


These guidelines reinforce Transport for NSW’s (TfNSW) ongoing commitment to sustainability; supporting project solutions that deliver environmental and social benefits while reducing life cycle costs.

1.1 Aim of the guidelines

The Sustainable Design Guidelines (the guidelines) seek to deliver sustainable development practices by embedding sustainability initiatives into the planning, design, construction, operations and maintenance of transport infrastructure projects.

The development of the guidelines has been influenced by the TfNSW Environment and Sustainability Policy and TfNSW Long Term Transport Master Plan. The guidelines incorporate the following key aims:

• Minimising impacts on the environment, whether through transport operations, infrastructure delivery or maintenance.

• Procuring, delivering and promoting sustainable transport options that achieve value for money and reduced life cycle costs.

• Developing, expanding and managing the transport network that is sustainable and climate resilient.

1.2 Structure of the guidelines

These guidelines are in five parts with appendices as follows:

• Part 1 Introduction outlines the sustainability and corporate drivers, scope and principles of the guidelines.

• Part 2 How to use the guidelines outlines a six step process starting from determining a guidelines pathway all the way through to obtaining a project rating under the guidelines.

• Part 3 Reporting describes the reporting requirements including timeframes, evidence requirements and accompanying tools.

• Part 4 Compulsory sustainability requirements provides full detail of each compulsory requirement to comply with the guidelines.

• Part 5 Review of the sustainable design guidelines outlines when and how the guidelines will be reviewed.

• Supporting document – includes:

− Appendix A – further detail on how the scoring system works.

− Appendix B – a step by step guide on how to use the electronic checklist to monitor a project rating under the guidelines.


− Appendix C – a library of supporting initiatives that projects can choose to utilise in order to meet compulsory requirements.

− Appendix D – supporting templates and forms.

− Appendix E – whole of life costing process to be utilised when selecting supporting initiatives.

− Appendix F – deemed to satisfy process for compulsory requirement 2.

− Appendix G – detail of the steel and timber requirements associated with compulsory requirement 12.

1.3 Why do we need the guidelines?

1.3.1 Sustainability drivers

Public transport delivers many social, economic and environmental benefits including:

• Fast, efficient, safe and affordable transport for passengers at peak and non-peak times.

• Connecting places and communities and enhancing social inclusion and local economic development.

• Enhancing economic opportunities in a range of activity centres across NSW.

• Encouraging people to transition from using cars which can significantly reduce traffic congestion and negative externalities such as noise, air pollution and greenhouse gas emissions.

There is, however, scope to continuously improve the sustainability performance of public transport and related infrastructure in a financially sustainable manner that delivers value for money through the life of the project.

1.3.2 Corporate drivers

The TfNSW Environment and Sustainability Policy outlines our commitment to delivering transport services, projects, operations and programs in a manner that balances economic, environmental and social issues to ensure a sustainable transport system for NSW.

One of the eight key objectives for the NSW transport system, set out within the NSW Long Term Transport Master Plan is to:

• Improve Sustainability – by maintaining and optimising the use of the transport network, easing congestion, growing the proportion of travel by sustainable modes such as public transport, walking and cycling, and becoming more energy efficient.

The Master Plan sets clear objectives and actions around sustainability to meet statewide issues and take up new opportunities, including setting:

• Initiatives to manage and minimise the environmental impacts of our transport system, including a coordinated approach to addressing environmental issues at all levels of transport planning, sustainable design guidelines for transport projects and better ways to assess the environmental and social benefits of projects.

The NSW Government Resource Efficiency Policy (GREP) sets a vision for a resource productive public sector that provides better services to the NSW community with less impact on the environment, establishing targets and goals for the NSW public sector to meet.

TRANSPORT FOR NSW T 8202 2200 F 8202 220918 Lee Street, Chippendale NSW 2008 | PO Box K659, Haymarket 1240

Transport is essential to the economic and social development of NSW. It provides access to jobs, housing, goods and services. It provides for the movement of people in their daily lives to improve their quality of life.

Transport for NSW, together with its key agencies NSW Trains, Sydney Trains, Roads and Maritime Services and State Transit Authority are committed to delivering transport services, projects, operations and programs in a manner that balances economic, environmental and social issues to ensure a sustainable transport system for NSW. We work towards achieving this by:

• Minimising impacts on the environment, whether through transport operations, infrastructure delivery, maintenance or corporate activities

• Procuring, delivering and promoting sustainable transport options that promote value for money

• Complying with relevant legislation

• Developing, expanding and managing the transport network in a sustainable and climate change resilient way.

We will continuously improve our performance in line with this Environment and Sustainability Policy by:

• Implementing sound governance practices to set, apply and monitor the policy across the portfolio

• Setting objectives and targets to improve management and performance in line with best practice

• Reporting on our performance

• Raising the awareness and capacity of our staff to build the policy into their day-to-day business

• Forming constructive partnerships with government, industry and the community on environment and sustainability issues

• Contributing to and influencing the strategic environment and sustainability agenda of the NSW Government.

Tim ReardonSecretary August 2015

Environment andSustainability Policy

The Environment and Sustainability Policy flows from our obligations under the Transport Administration Act 1988 for “the delivery of transport services in an environmentally sustainable manner” and is reflected in our Corporate Plan “Connections - Towards 2017”.

I commend the policy to all within the Transport cluster agencies.

The Transport Outcomes Framework is an overarching framework for TfNSW that articulates how we contribute to bigger picture economic and social outcomes in NSW. The framework is partially comprised of a hierarchy of outcomes that TfNSW is working towards over the long term. The framework includes three levels of outcomes:

• Level one (L1) are the highest outcomes that Transport delivers for NSW aligned with the legislative objectives for Transport agencies (Transport Administration Act 1988).

• Level two (L2) are the intermediate outcomes required to deliver L1 outcomes and are therefore more specific.

• Level three (L3) are a further breakdown of the building blocks required to deliver the L2 outcomes.

Figure 1 provides a snapshot of the L1 and L2 outcomes that the Transport cluster is working towards. It includes L1 and L2 outcomes directly related to Environment and Sustainable transport delivery respectively. Figure 1 highlights the outcomes that the sustainable design guidelines support.

1.3.3 Key TfNSW sustainability policy documents

TfNSW have a number of other key sustainability related policy documents that respond to the key drivers outlined in section 1.3.2. Figure 2 below highlights some of these documents and how they fit within the organisation.

Figure 2: TfNSW Sustainability Policy Context

Transport Environment and Sustainability Policy FrameworkThe Framework is a collective and coordinated approach to deliver the NSW Government’s environmental and sustainability agenda across the Transport cluster. The Framework is outcomes based and seeks to improve Transport’s

environmental sustainability performance.

Environment Statement of CommitmentThe Statement of Commitment complements the TfNSW Environment and

Sustainability Policy and addresses ISO14001 requirements specifically for I&S work activities. It outlines the key principles for delivering on our commitment to deliver

transport infrastructure, fleet and technology that is sustainable and minimises detrimental impacts and risks to the natural environment and the community.

Transport for NSW Environment and Sustainability Strategic Plan 2016-2018The objective of the Strategic Plan is to deliver a sustainable transport system by:

1. Developing strategies and programs that integrate environment andsustainability into our business to create an environmentally aware culture.

2. Developing and implementing the TfNSW Environmental Management System consistent with the integrated Management System Framework.

Sustainable Design GuidelinesThe guidelines have been in place since 2009 and set out requirements to be

incorporated into the project lifecycle to enhance sustainability outcomes.

Carbon Estimate and Reporting Tool

The CERT was published in late 2015 and provides a tool to consistently

capture and track project greenhouse gas emissions. In line with requirements outlined in the

sustainable design guidelines.

Climate Risk Assessment GuideThe Guide was published in early 2016 and provides guidance on how to undertake climate risk assessments, in line with the requirements outlined in the

guidelines.

There are also a number of policy drivers that relate to specific compulsory requirements in the guidelines. These are outlined in section 4.3.


1.4 Who will use the guidelines?

The guidelines are aimed primarily at planning, design, construction, operations and maintenance professionals involved in projects being delivered by Infrastructure and Services Division (I&S) of TfNSW. They will be of particular interest to:

• project managers

• engineers

• design managers

• cost planners

• environmental managers

• construction managers

• maintenance staff

• asset operators and maintainers

• procurement and contract managers

• community consultation managers

• sustainability managers

• staff involved in project business case development

1.5 What do the guidelines cover?

The guidelines apply to all infrastructure projects delivered by I&S Division of TfNSW and cover the following sustainability themes:

Energy and greenhouse

Climate resilience

Materials and waste

Water

Pollution control

1.6 The context of these guidelines

These guidelines should be used in conjunction with other guidelines relevant to infrastructure delivery and operations. Any statutory or legislative requirements (including codes, regulations or standards) take precedence over any of the outcomes or initiatives within this document.

1.7 Principles applied to version 4.0

This updated version of the guidelines are underpinned by a number of key principles, including:

1. Compulsory requirements are quantifiable where practicable.

2. The guidelines are scalable to different sized projects.

3. Allows projects to focus on material issues to achieve value for money outcomes.

4. Alignment with the Infrastructure Sustainability Council of Australia (ISCA) tool is considered.

5. Innovation and positive legacy initiatives are considered.

6. Relevant requirements under the NSW Government Resource Efficiency Policy (GREP) are incorporated.

7. Implement a whole of life process to ensure optimisation of the asset whole of life cycle including feasibility, design, construction, operations, maintenance and disposal.

8. Reduction of operational and maintenance costs are achieved.

9. Ease of reporting through accompanying online tool (to be developed) is realised.

10. Evaluation of benefits realisation.

2. How the guidelines work

Barangaroo Ferry Hub construction site.


These guidelines are to be used by the project team at each project deliverable stage e.g. – feasibility/definition design, preliminary design etc. The application of the guidelines is a collaborative process requiring multidisciplinary discussion within a project team when identifying the initiatives that are applicable to a project. Infrastructure and Services (I&S) Sustainability and Systems team is able to assist with project team workshops on the guidelines and provide specialist support, however the process must be led by the technical and project managers and embedded into the project methodology.

2.1 Sustainability initiatives and their value

There are 14 compulsory requirements and 2 sub requirements that project teams are required to implement when there is confirmation that these individual initiatives are applicable to the project.

Each compulsory requirement has an associated list of supporting initiatives. Project teams can utilise one or more supporting initiatives to help meet the compulsory requirements. Note: projects are not restricted to using only the supporting initiatives listed. Table 2 below provides more explanation on the types of sustainability requirements.

Table 2: Types of sustainability requirements

Importance Definition

Compulsory requirement These requirements may relate to one of I&S’ organisational priorities or are considered fundamental to the delivery of sustainable transport infrastructure. If a requirement is considered applicable, then a project must meet it. Refer to section 2.2.3 for further detail on determining applicability.

Note: That there are two sub requirements that assist in meeting two of the compulsory requirements. These are listed as compulsory requirement 2A and 8A.

Supporting initiative Project teams may choose to utilise supporting initiatives (see Appendix C) to meet a particular compulsory requirement or use initiatives beyond the scope of those listed. This allows project teams the flexibility to choose appropriate initiatives to meet their compulsory requirements in line with specifications and standards. When submitting evidence against a project’s compulsory requirements the supporting initiatives utilised must be specified. Refer to section 3.2 for further detail on evidence requirements.

Each compulsory requirement has between 1 and 5 performance levels (P1 – P5) with the minimum P1 level reflected in the wording of the compulsory requirement. The P1 levels are what are deemed to be required at a minimum to meet TfNSW’s sustainability agenda. The technical and financial feasibility (and benefits) of meeting the P1 levels have been tested through both consultation and financial evaluation.


Table 3: Example of requirement with multiple performance levels (5)

Compulsory requirement 1

All projects with a CapEx > $15 million to reduce construction related GHG emissions by a minimum 5% from the project baseline GHG footprint established using the Carbon Estimate and Reporting Tool (CERT).

Performance levels for rating

≥ 5% ≥ 10% ≥ 15% ≥ 20% ≥ 25%

Some requirements include only a single performance levels e.g. – compulsory requirement 2A.

Table 4: Example of requirement with a single performance level

Compulsory requirement 2A All new electrical equipment to be at least market average star rating. In categories where no star ratings are available, equipment purchased should be recognised as high efficiency either by being ENERGY STAR accredited, in a high efficiency band under Australian Standards or being above-average efficiency of Greenhouse and Energy Minimum Standards (GEMS) registered products.

Performance levels for rating P1/ P2/ P3/ P4/ P5

All new electrical equipment to be at least market average. In categories where no star ratings are available all equipment must be Energy star accredited or above average GEMS registered.

The policy drivers for each of the compulsory requirements are outlined in section 4.3. The performance levels incrementally increase performance against each requirement to encourage beyond minimum (P1 level) compliance through the use of the rating system. Refer to sections 2.2.5 and 4.3 for further details on the performance levels.

2.2 How to use the guidelines

A key component of the guidelines process is undertaking life cycle costing, this is particularly relevant to selecting supporting initiatives (refer to section 2.2.4).

When selecting supporting sustainability initiatives the following requirements must be applied. The sustainability initiatives must:

• Minimise (or reduce from business as usual) whole of life costs over the life of the project (refer to Life Cycle Costing Management Standard T MU AM 01001 ST for guidance).

• Demonstrate equal or reduced (from business as usual) operational and maintenance burden/costs as a measure of their effectiveness.

Projects must apply the life cycle costing process and supporting tool described in Appendix E.

http://www.asa.transport.nsw.gov.au/sites/default/files/asa/asa-standards/t-mu-am-01001-st.pdf


There are six key steps to using the guidelines:

• Determining the sustainable design guidelines pathway

• Setting a target rating

• Applicability test

• Selecting supporting initiatives including life cycle assessment and evaluation

• Implementing and tracking

• Determining your project rating

2.2.1 Determining the sustainable design guidelines pathway

There are two potential pathways that can be pursued:

1. Full checklist process is required to be completed by the construction contractor. Note: The preliminary and detailed designers are still required to start incorporating relevant design requirements into design and commence reporting. Refer to section 3 for detail on reporting requirements.

2. Specific requirements are specified in the contract for the construction contractor. Note: Design requirements must be incorporated into the design and reported on by the preliminary and detailed designers.

Figure 4 below outlines the process that must be used to determine a projects sustainable design guidelines pathway.

Figure 4: Process to determine a projects Sustainable Design Guidelines pathway

Feasibility/Business CaseAs part of the feasibility stage the project team should identify applicable sustainable design guidelines requirements and potential initiatives to be implemented (including life cycle costing) assessment and commence reporting.

Detailed DesignDetailed designer to incorporate relevant requirements into design. Reporting is required. Refer to section 3 for detail on reporting requirements.

Pathway 2Construction requirements incorporated into contract (by designer). Reporting on construction requirements required in line with section 3.

Preliminary DesignPreliminary designer to start incorporating relevant design related requirements into the design. Specific initiatives should be proposed, reviewed and endorsed by TfNSW. Reporting is required in line with section 3.

Pathway 1Full guidelines checklist required to be undertaken by contractor. Both design and construction requirements are required to be implemented and reported on in line with section 3.

Will detailed design be undertaken partially or fully by someone other than the construction contractor?

Is the contract type to be construct only?

YES

NO

NO

YES

Note: if a project delivery stage is being revisited e.g. – due to a design/scope stage, the sustainable design guidelines pathway must be reviewed as part of this process.


2.2.2 Setting a target rating

A points based system (based on the performance levels) is used to determine the project rating under the guidelines. There are five possible ratings that can be achieved (pass, bronze, silver, gold and platinum). Figure 4 outlines what a project team needs to consider when setting a minimum target rating. Refer to section 2.2.5 for further details on how a rating is determined.

Figure 5: Criteria for setting a minimum Sustainable Design Guidelines rating

Does the project trigger compulsory requirements that have multiple performance levels (2 or more) within them? Refer to section 4.2 and 4.3

Does the project have a CapEx>$50million?

YESNO

YES NO

Project can not achieve a rating above a pass level(Refer to Section 2.2.5 for further detail)

Project must meet the requirements of its applicable compulsory requirements in order to comply with the guidelines

Minimum Silver RatingProject must achieve a minimum silver rating under the guidelines

Minimum Pass RatingProject must achieve a minimum pass level rating


Project teams can choose to set a voluntary target rating which is above the minimum requirements specified in Figure 4. When setting a voluntary target rating project teams should undertake a cross discipline workshop including lifecycle assessment at an early design stage (i.e. – definition or preliminary design) to:

• Establish what performance level is thought to be both achievable on a project and present a value proposition for each applicable compulsory requirement, including based on a life cycle costing exercise.

• Identify any priority areas for the project e.g. – energy reduction.

• Calculate a voluntary target rating for the project. Note: Projects may choose to set both a base target and stretch target as part of this process.

• Consider cost implications as well as be clear on benefits and the value proposition for going above minimum requirements. Cost implications shall include details of operations and maintenance components.

Any voluntary target rating should be documented within any subsequent project documentation e.g. – contract documents, project sustainability strategy etc.

2.2.3 Applicability Test

Projects are only required to meet compulsory requirements that are applicable to the project. There are two methods to determine whether a compulsory requirement is not applicable for a project:

1. Thresholds: the project does not trigger the threshold specified for the compulsory requirement e.g. – a threshold CapEx of >$15 million has been set for the requirement but the project has a CapEx of $10 million. Refer to section 4.2 and 4.3 for specific details on the thresholds set for each of the compulsory requirements.

2. Outside of scope: if the project triggers the threshold associated with a given compulsory requirement however the requirement is completely outside of project scope, the project team can rule this requirement to be not applicable, subject to agreement with the I&S Sustainability and Systems team. When ruling out a compulsory requirement where the threshold has been triggered a strong auditable justification must be provided e.g. – the compulsory operational water requirement could be ruled out if there is no operational water use for the project. In order to rule out a compulsory requirement where the threshold is triggered the project team must submit a memo (refer to template provided in Appendix D) to the I&S Sustainability and Systems team for review and approval.

Note: If a project does not trigger any compulsory requirements then the project is not required to comply with the Sustainable Design Guidelines.


2.2.4 Selecting supporting initiatives

Once a project team has determined which compulsory requirements are applicable to the project, the team must select what supporting initiatives they will implement in order to meet their compulsory requirements. Note: Project teams can choose from the list of supporting initiatives provided in Appendix C however they are not restricted to using only the supporting initiatives listed.

It is strongly recommended that this selection process be undertaken in a cross discipline workshop or series of smaller workshops. Participants should include but are not limited to:

• sustainability managers

• environment managers

• engineers

• design managers

• procurement and contract managers

• quantity surveyors/ cost planners

• operations and maintenance personnel

• community consultation managers

• asset managers

• investment managers

When selecting supporting sustainability initiatives the following requirements must be applied. The sustainability initiatives must:

• Minimise (or reduce from business as usual) whole of life costs over the life of the project (refer to Life Cycle Costing Management Standard T MU AM 01001 ST for guidance).

• Demonstrate equal or reduced (from business as usual) operational and maintenance burden/costs as a measure of their effectiveness.

Projects must apply the life cycle costing process and supporting tool described in Appendix E.

2.2.5 Implementation and tracking

The guidelines apply to the whole asset lifecycle and the earlier they are considered the easier it is to achieve sustainability outcomes and compliance with these guidelines. Table 3 below provides a guide on what needs to be considered/completed at key project stages.

http://www.asa.transport.nsw.gov.au/sites/default/files/asa/asa-standards/t-mu-am-01001-st.pdf


Table 5: Key tasks relevant to each project stage

Project stage Key activities

Feasibility stage or business case or definition design

• Identify what sustainability requirements are relevant to the project.

• Identify guidelines pathway including specific initiatives (refer section 2.2.1)

• Ensure initiatives are costed (CapEx and life cycle costing), options are reviewed and endorsed as part of project budgeting processes

• Identify target rating for the project (refer section 2.2.2)

• Ensure target rating and initiatives are integrated into project documents such as business requirements specifications

• Reporting to commence (refer to section 3).

Preliminary design • Confirm the requirements identified in the feasibility/ business case stage are still relevant

• Sustainability requirements and specific initiatives should be reviewed, updated and locked in (where appropriate) e.g. – in the scope of works/works brief at a minimum

• Review and update of lifecycle costing process

• Reporting required (refer to section 3).

Detailed design • Design related requirements to be incorporated into project design

• Review and update of lifecycle costing process


Construction • Sustainability requirements (both design and construction related) to be implemented


Completion • Final report required to demonstrate compliance with requirements and identify the final project rating.

Data and evidence submitted will be used as part of TfNSW’s evaluation of benefits realisation (refer to section 5).

2.2.6 Determining your project rating

A project’s rating will be automatically calculated through the use of the reporting tool that accompanies the guidelines (refer to section 3.3).

Further details on how the scoring system works can be found in Appendix A.

Table 6: Requirements to achieve Sustainable Design Guidelines rating

3.1 Reporting timeframes

Reporting against the sustainable design guidelines is required at:

• Feasibility stage/ business case/ definition design

• Preliminary design

• Detailed design (SDR and CDR or equivalent)

• Six monthly during construction

• At project completion.

If a project has multiple design packages/packages of work being undertaken on different timelines, the project must reach agreement with TfNSW Sustainability and Systems team on when they will need to submit documentation for review through a memo process (refer to Appendix D for memo template). There are two options as outlined below:

1. The project identifies all major design packages and selects an appropriate date for submission based on when the majority of design will be at the reporting timeframes listed above (i.e. – detailed design).

2. The project can submit different sustainable design guidelines checklists for different design packages. This option is recommended particularly where large packages of works are being delivered by different designers and/or contractors etc. Note: if this option is pursued each separate package of work would need to demonstrate that the minimum sustainable design guidelines rating set for the project has been achieved.

Supporting documentation and evidence should be supplied as it becomes available. All evidence must be submitted at the time of project completion to the I&S Sustainability and Systems team.

3.2 Supporting documentation and evidence

A project will be required to submit supporting documentation and evidence to demonstrate compliance against the applicable compulsory requirements for the project. At a minimum this documentation will need to:

• Demonstrate compliance with the relevant compulsory requirement.

• Outline initiatives implemented in order to meet the compulsory requirements. Note: This includes supporting initiatives provided in the guidelines as well as any other initiatives.


The types of supporting documentation and evidence may include:

• Specialist reports (e.g. – climate risk assessment)

• Data tracking sheets (e.g. – waste tracking)

• Existing tools (e.g. – carbon estimate reporting tool (CERT))

• Plans

4.2 Thresholds for compulsory requirements

To ensure that the compulsory requirements applied to a given project are compatible with the nature and scale of the project, thresholds have been applied to each of the compulsory requirements. In order for a compulsory requirement to be deemed applicable to a project the relevant threshold must be triggered. There are two types of thresholds that have been assigned to the compulsory requirements including:

• CapEx related thresholds. These thresholds are purely based on the capital expenditure of the project exceeding a given value. There is one CapEx related thresholds within the guidelines –

− >$15 million

• Non-CapEx related thresholds. These thresholds are based on criteria other than capital expenditure. There are three non-CapEx related thresholds within the guidelines including –

− All project generating >300m3 of spoil

− All projects with new effective impervious area with a continuous area >1000m²

− All projects with non-significant biodiversity impacts

Figure 6 provides a summary of how the different thresholds apply to each of the compulsory requirements.

4.3.1 Compulsory Requirement 1 – Construction GHG emissions


All projects with a CapEx > $15 million to reduce construction related GHG emissions by a minimum 5% from the project baseline GHG footprint established using the Carbon Estimate and Reporting Tool (CERT).

Description I&S projects can reduce the construction related greenhouse gas (GHG) emissions through materials choice, optimising design and construction practices on site. Projects are required to establish a baseline footprint using the Carbon Estimate and Reporting Tool (CERT) and demonstrate a reduction of construction related GHG emissions of at least 5% from the established project baseline (Note: The project baseline is automatically generated within the CERT tool, refer to CERT user manual for details). The CERT was developed to simplify and provide consistency in GHG emissions assessment and reporting across all I&S projects.

ISCA alignment with ISCA v1.2

The Carbon Estimate and Reporting Tool (CERT) developed by I&S will support compliance with this requirement and has been developed to align with the design and construction stage reporting requirements associated with ISCA credits Ene-1 and Mat-1. The P3 and P5 performance levels correspond to Level 2 and Level 3 in the ISCA Ene-1 credit. Note: The following differences to the ISCA Ene-1 credit:• Emissions associated with operation are not currently captured within the CERT and

will need to be captured separately.

• Embodied emissions associated with materials use are captured within CERT but are captured in the ISCA Mat-1 credit rather than Ene-1. Note: That the target reductions in materials impacts are 15% for Level 2 and 30% for Level 3 in Mat-1. These reductions are measured in EnviroPoints (which include GHG emissions as well as other impact categories).

• Baseline (base case) footprints may be different.

4.3.2 Compulsory Requirement 2 – Operational energy

Compulsory Requirement 2

Buildings are required to be designed and built to reduce energy consumption:

• Covered or uncovered areas shall meet pre-requisite requirements for services (Appendix F, Section 3).

• Enclosed building spaces shall meet the performance targets of the energy modelling pathway (P2-P5).

• Where enclosed building space cost < $10 million the prescriptive pathway may be followed in lieu of energy modelling (P1).

Pathways flowchart

Project Start CapEx Estimate

Project concept creation and CapEx estimation.

The project is separated into ‘Building’ and ‘Non-Building’ components.

The scope of CR2 is isolated to the ‘Building’ component of the project.

Projects completing the Prescriptive Requirements pathway are eligible for a rating equivalent to P1/P2 performance level.

The Energy Modelling path must achieve at least 10% energy saving compared to a ‘reference’ model in order to pass.

OUTSIDE OF SCOPE OF CR2

The ‘Building’ is further separated into ‘Covered & Uncovered Areas’ and ‘Enclosed Building’ portions.

‘Covered & Uncovered Areas’ must comply with the C&UA Specific Requirements before the project may proceed.

Satisfactory compliance with Prescriptive Requirements leads automatically to a ‘pass’ and completion. It is not tested for performance.

The Energy modelled building is evaluated against the Reference Building for quantifiable energy consumption savings.

Projects processed by default along the Energy Modelling pathway.

Enclosed Building projects < $10M may elect to proceed along the Prescriptive Requirements pathway in lieu of Energy Modelling.

Projects completing the Energy Modelling pathway are eligible for a P1-P5 performance level rating.

Description The scope of Compulsory Requirement 2 (CR2) is limited to the ‘Building’ component of a project.

Covered and Uncovered Areas Specific Requirements‘Covered and Uncovered Areas’ are required to comply with the Specific Requirements of CR2 irrespective of other building components.







Description Energy Modelling Pathway‘Enclosed Buildings’ are required to follow the Energy Modelling pathway to prove at least a 10% energy usage improvement over the NCC (BCA) Section JV3 Reference Building. Initiatives from, but not restricted to those listed in Appendix F, Section 6 may be considered in achieving energy consumption reductions.

CR2 assumes that the NCC JV3 Reference Building is used as the reference building regardless of building classification or requirement to comply with NCC (BCA). An alternative benchmark may be considered provided an equivalent energy saving potential as compared to NCC (BCA) Section J can be demonstrated.

Prescriptive Requirements Pathway‘Enclosed Buildings’ with a component cost < $10M may elect to follow the Prescriptive Requirements pathway in lieu of the energy modelling pathway. When electing to follow the Prescriptive Requirements pathway, all the prescriptive requirements shall be met through application of recognised good engineering practice. Since the Prescriptive Requirements pathway cannot quantify actual kWh reduction, projects on the Prescriptive Requirements pathway will not demonstrate a % reduction but will demonstrate that energy efficiency measures have been implemented, and therefore will achieve P1/P2 performance level.

On-site renewable energy generationTfNSW is seeking to incorporate renewable energy generation on applicable building assets. However, renewable energy installations must not preclude energy efficient design. The proposed building must demonstrate a minimum 10% improvement (P1/P2 performance level rating) through the energy modelling pathway prior to inclusion of on-site renewable energy generation in the credit calculations.

Once a 10% improvement has been successfully demonstrated, the on-site renewable energy generation (e.g. solar PV) may be used to counteract the kWh energy expenditure of the proposed building in order to reach P3 – P5 score. Projects demonstrating compliance with CR2 through the Prescriptive Requirements pathway may still implement renewable energy installations. Such projects may be awarded P3 – P5 without energy modelling, subject to TfNSW approval.

Compliance with this requirement aligns with ISCA’s requirements under Ene-1, ‘Energy and carbon monitoring and reduction’. Within this credit ISCA awards projects that reduce emissions from key emission sources. ISCA requires emissions reduction to be measured in line with a base case footprint. For level 2 achievement, emissions reductions must be across both Scope 1 and Scope 2 emissions. For level 3 achievement important Scope 3 emissions must also be considered but need not be used to achieve the reduction. Note: The following differences to the ISCA Ene-1 credit:• Ene-1 target reductions are for infrastructure lifecycle emissions (construction and

operation combined).

• Ene-1 targets at 15% reduction at Level 2 and 35% at Level 3 whereas this compulsory requirement targets 10%.

• Baseline (base case) footprints may be different.

4.3.7 Compulsory Requirement 6 – Water sensitive urban design


All new effective impervious area with a continuous area >1000m² to be treated through water sensitive urban design.

Description Water Sensitive Urban Design (WSUD) is the industry term describing the integration of water cycle management into planning, design and construction of the built environment through the replication of natural processes into treatment of water in a constructed environment. The main interaction with the water cycle in the development and operation of TfNSW projects is through the management of stormwater, where the amount of hard surface area created during construction increases the volume and decreases the quality of water entering downstream waterways.

This requirement relates to continuous areas of new effective impervious area >1000m² (refer to definitions below). Projects that have areas of new effective impervious area that trigger this threshold will be required to meet the following water treatment levels for the area specified in the relevant performance levels:• 90% retention of gross pollutants

• 85% retention of the average annual load of suspended solids

• 65% retention of the average annual load of Total Phosphorus

• 45% retention of the annual load of Total Nitrogen

• maintain the 1.5 year Average Rainfall Interval (ARI) peak discharge to pre-development levels

For higher performance levels the project must meet the treatment levels specified as well as implement other WSUD related initiatives as outlined in the performance levels below.

Potential supporting initiatives that a project can choose to use to meet this requirement are listed in Appendix C. The TfNSW Water Sensitive Urban Design Guideline – Consultation Draft provides further detail on different WSUD initiatives and where they are most suited to be used.

All projects located within water catchment areas should consider setting water quality targets for the project in line with best practice. This is most effective when established as part of the environmental assessment process.

ii. undertake sustainable procurement training for high impact suppliers.

Definitions High impact suppliers

Refers to materials/services that have known (or potentially) significant environmental, social or socio-economic impacts or opportunities. Level of spend and ability to influence are criteria that can be applied to identify suppliers for sustainability training, as well as a contractor’s corporate sustainability policy commitments. Alternatively a risk assessment may reveal areas of focus across a project’s various supply chains.

For further guidance refer to:• British Standard BS 8903:2010 Principles and Framework for

Procuring Sustainably – Guide.

• ISO 20400 Sustainable Procurement – Guidance.

• ISCA Technical Manual Pro-2 credit.

Steel and timber requirements

Appendix G details the steel and timber sustainable procurement requirements. These requirements have been developed in response to a high impact supplier analysis undertaken by TfNSW. Projects should include steel and timber as part of their sustainable procurement strategy and sustainability training program (where steel and/or timber products are being used) to ensure these requirements are met.

Sustainability training

Contractors can use their discretion to determine the training scope and needs of their organisation and suppliers – but it must at a minimum address ‘high impact’ suppliers. Supply chain sustainability training will ideally cover environmental, social and economic topics. Examples include waste management, energy efficiency, human rights and modern slavery, apprenticeships and traineeships, local sourcing, and worker health and safety.

In addition to the Australian Supply Chain Sustainability School, other training options include internal sustainability education programs offered by contractors to their procurement staff/supply chain, and the Green Building Institute’s Green Tradies program. A combination of training programs may be appropriate.

Where a supplier has recently undertaken sustainability training prior to being engaged on the project, and that training meets the intent of this training requirement, it should be added to the Sustainability Training Register.

4.3.16 Compulsory Requirement 14 – Innovation and project legacy


The project is awarded at least 1 point for a single initiative against the ISCA Innovation Credit Inn-1

OR The project makes a contribution to industry and/or the local community in line with the project legacy categories specified (Note: The requirements are determined by CapEx).

Description This requirement encourages innovation and project legacy. There are two pathways in which a project can meet this compulsory requirement. They can either pursue an innovation in line with the ISCA innovation credit Inn-1 or they can implement other project legacy or community initiatives in line with the categories specified below.

Pathway 1: ISCA Inn-1 CreditUnder the ISCA innovation credit (Inn-1) a project can be awarded up to 10 points as follows:• Up to 10 initiatives can be submitted.

• Each verified initiative will be awarded one point unless it is an Australian 1st (2pts), World 1st (3 pts), or indicated otherwise elsewhere

• Each initiative must meet one or more of the following five criteria:

− innovative technology or process

− market transformation

− improving on credit benchmarks

− innovation challenge

− global sustainability

If the project is registered with ISCA the points awarded will be entirely at the discretion of the ISCA verifiers.

Note: Projects not pursuing an ISCA rating can still pursue pathway 1 under Compulsory Requirement 14.

Pathway 2: other project legacy or community initiativesIf a project is not pursuing an innovation that meets the ISCA innovation credit (Inn-1), the project must achieve a certain number of points through implementing project legacy initiatives. Project legacy initiatives can address any of the following areas:• Knowledge sharing/ Educational initiatives (refer to ISCA Technical Manual for

suggested approaches to knowledge sharing).

• Initiatives to support renewable energy transport forms.

• Initiatives to support active transport and integration with other modes and forms of transport.

• Initiatives to provide communication networks in metro areas.

• Future proofing initiatives.

• Shared/adaptive reuse initiatives.

• Community facilities or community identity related initiatives.

• Initiatives to monitor resource use within buildings.

Note: That the performance levels vary depending on the project value, with different performance levels specified for the following project values:• CapEx <$15 million

• CapEx ≥$15 million – <$ 50 million

• CapEx ≥$50 million

The project must self-assess each proposed initiative against the criteria in the below table to determine how many points the initiative/s are worth.

60 beams from the Monorail Removal project were reused to build a temporary bridge structure at Norwest as part of the North West Rail link. The temporary bridge structure allowed the project to continue construction of the new station with Brookhollow Avenue only being closed for three months rather than three years resulting in reduced community impacts.


5. Review of the Sustainable Design Guidelines

Newtown Station upgrade project.


The Guidelines will be reviewed on an annual basis to consider the following at a minimum:

• The effectiveness of the current compulsory requirements, and whether any changes are required.

• Any new emerging areas where a compulsory requirement should be developed.

• Whether the weighting associated with each compulsory requirement still reflects I&S organisational priorities and areas of material impact.

• Evaluation of benefits realisation.

Beneficial reuse Beneficial reuse includes but is not limited to activities associated with reuse on site or offsite, where fit for purpose and appropriate approvals have been obtained.

Note: Beneficial reuse does not include material being treated as waste and being sent to landfill, unless the project can demonstrate that the material is genuinely inert and is being used for landfill capping material.

CERT Carbon Estimate Reporting Tool – a tool that has been developed to provide consistency in Greenhouse Gas (GHG) emissions assessment and reporting across all I&S projects, and to streamline and simplify the GHG assessment process for I&S, its service providers/contractors and its stakeholders.

Construction related GHG emissions

GHG emissions associated with the delivery of a construction project including scope 1 emissions (i.e. – direct emissions from site such as fuel combustion), scope 2 emissions (i.e. – upstream emissions from electricity purchased for site) and scope 3 emissions (i.e. – the embodied emissions in the materials used to deliver the project). Refer to CERT for details of the emissions that must be reported on.

Construction water All water used in site establishment, construction and site decommissioning including water used to supply site offices and sheds (excluding drinking water and water used in concrete). Note: Excess water captured on site and discharged without reuse is not considered construction water.

Covered area Refers to a building space covered only by roof and is otherwise exposed to outdoor ambient air. This includes a platform with a canopy.

Critical design review (CDR)

CDR is a design review process that takes place at or close to the completion of the detailed design phase. The primary purpose is to ensure that the design appears to be suitable to proceed with construction/fabrication of hardware items or coding of software. In cases where the project is limited to design i.e. – separate design and construct contracts are involved, the CDR will form a major input for determining whether the requirements of the design contract have been met.

DTS Deemed to satisfy

Effective impervious area Impervious area in the catchment that is directly connected to waterways (including stormwater drains) (i.e. precipitation falling on that area is effectively transported to the receiving waterway), thought to be a better predictor of ecosystem alteration to urban waterways when compared to total impervious area. Note: roof space is considered effective impervious area.

Enclosed building Refers to building spaces within above ground structures enclosed by roof and walls. The whole of an underground station is considered as an enclosed building.

High impact suppliers Refers to materials/services that have known (or potentially) significant environmental, social or socio-economic impacts or opportunities (refer to British Standard BS 8903:2010 for further guidance). Level of spend and ability to influence are also criteria that can be applied to identify suppliers for sustainability training.

The contractor can determine which organisations/suppliers are required to undertake training and to what level.
